JAR-CAP TOO L.

SPECIFICATION forming part Of Letters Patent NO. 724,399, dated. March 31, 1903.

Application filed December 7, 1901. Serial No. 85,048. (No model.)

To all w/tam zit may concern:

Be it known that I, J OHN'GODFREY Rosan- BERG, a citizen of the United States of America, and a resident of the city of Seattle, in the county of King and State of lVashington, have invented certain new and useful Improvements in Jar-Cap Tools, of which the following is a specification.

This invention relates to an improved jarcap tool which is adapted to surround a jarcap after the cap has been placed upon the jar and is provided with a means for engaging the flange on the cap to bend same evenly upon the jar, thus insuring a perfect-fitting ar-cap.

With reference to the drawings filed herewith and bearing like reference characters for corresponding parts throughout, Figure 1 is a plan view of my improved tool. Fig. 2 is a transverse section of same on line 2 2 of Fig. 1. Fig. 3 is a plan View of the clamping portion of the tool slightly modified. Fig. at is a transverse section on line 4 4 of Fig. 3,- and Fig. 5 is a perspective of an ordinary form of fruit-jar with a screw-cap and indicates my improved tool in position as ordinarily employed.

This invention includes an improved construction in tools of the nature indicated and also comprehends any means whereby that portion of a cap serving to seal a jar or like receptacle can be repeatedly remodeled or shaped, and thereby prolong the usefulness of the cap and efiect a more perfect joint. As now considered this remodeling device is designed to operate upon ordinary screwcaps having a peripheral flange, as 1, Fig. 5, and is adapted to remodel or shape this flange to effect a more perfect fitting thereof. to its seat and render the cap capable of repeated use. In the present embodiment the device comprehends a suitable carrier, as 2, adapted as means to conveniently support and apply the working point and comprising in the present instance a spring tool or wrench of a construction suitable for use in seating and unseating the cap. This tool is rendered with the usual circular portion or partial annulus, as 3, adapted to embrace the cap, and suitable separated handles, as 4', by which the wrench is closed to grip the cap, and comprehends a carrying part of the remodeling device, which shall be rotatable about the jar and cap at will to conveniently apply a working or pressure point, as 5, to shape the cap. As readily understood, when the tool is open it can be moved about the cap, and consequently by arranging the working or pressure point 5 thereon at a suitable point it can be made to operate upon the flange or like portion of the cap, and by exerting downward pressure on handles 4 as the tool is revolved this working point is made to press upon flange 1 and shape it to the seat afiorded by the usual shoulder found on the'class of fruit-jars indicated, and thus a screw-cap is remodeled to effect a tight closure after being seated in the usual manner. In the present instance the working or pressure point 5 is conveniently embodied at the base of one of the handles 4 and is given suitable lateral projection to bring the active surface thereof in close proximity to the upper surface of flange 1 of a screw-cap when the annular-like portion 3 of the device oncircles the part of the cap adapted for the grip of a tool. This working point comprises a projection of any suitable construction arranged with an active surface adapted to press upon the flange of the cap and may embody a suitable antifriction roller or wheel, as 6, Figs. 3 and 4, as the active surface, which is suitably mounted on a journal, as 7, fixed at the base of one of the handles 4:.

As now considered the carrier is formed of a single piece of wire of suitable resilient properties to impart to the annulus-like portion 3 the necessary elasticity to cause it to open and release the cap when the handles are released, and this partial annulus is conveniently formed by bending a suitable central portion of the wire to the desired circular form, when the remaining end portions are bent laterally therefrom at suitable separation and each conveniently brought to af ford a plurality of stems to give stilfness and rigidity by bending them outwardly from each other and then inwardly to the circular por tion, to which they are suitably connected, as by soldering, thus forming strong substantial handles of elongated-U shape, which afford an easy grasp and render it possible to make the tool of comparatively light and inexpensive material.

When the tool is constructed as above, the working or pressure point 5 is preferably conveniently formed of a piece of Wire brought to substantially U shape, and the ends thereof are conveniently secured to the stem of one of the handles 4 in the desired position by soldering, or the point may be substantially L-shaped, with a suitable roller, as 6, journaled on the foot 7 thereof, as indicated in Figs. 3 and A, to offer an antifriction bearing-surface.

hen it is desired to remodel or shape the flange of the jar-cap, the tool is rotated about the seated cap with the pressure-point traversiug the flange under pressure brought to bear by forcing the attendant handle 4' downwardly as the tool is moved about the cap. In this manner the flange of the cap is made to conform to its seat, and any irregularities therein or the like occasioned by the use of a pry in removing the cap previously are straightened out and the flange thus rendered true and brought to a perfect fit.

It will be understood that the form of the working or pressure point is susceptible to various modifications without materially departing from the essence of the invention and that its embodiment with a tool of the form described is a mere matter of choice in the selection of a suitable carrier adaptable for the required operation about the jar-cap to apply the working point.

Having thus described my lnvention, what I claim as new, and desire to secure by Letters Patent, is

1. A jar-cap remodeling and fitting device, comprising a tool having a divided annular portion and clam pin g-handles, and a Working point adjacent the base of said handles and projecting downwardly below the handles and adapted to engage the flange of a jar-cover and press the same in shape.

2. A jar-cap remodeling and fitting device, comprising a spring jar-cap tool having a divided annular portion and outwardly-projecting arms forming clamping-handles, and a downwardly-projecting working point adjacent the base of said arms having an active pressure-surface.

3. A jar-cap remodeling and fitting device, comprising a tool. having a divided annular portion and double handles, and means connected to both members of one of the handles near its base and projecting downwardly to engage the flange of a jar-cover and press the same in shape.

4. A jar-cap remodeling and fitting tool, comprising a divided annular portion to surround the cap, a pair of double handles formed integral with the annular portion, and a frame slidably mounted upon one of said handles carrying a downwardly'projecting contact to engage the flange of a jar-cap and press the flange in shape.

5. A jar-cap remodeling and fitting tool, comprising a divided annular portion to surround the cap, a pair of double handles formed integral with the annular portion, a frame slidably mounted upon one of said handles, and a roller journaled in the frame to engage the flange of a jar-cap and press the same in shape.
